SCRQALPER-BAR SUPPORT FOR PASTING-MACHIN ES.

Specification of Letters Patent. Patented July 29, 1919 Originalapplication filed April 25, 1918, Serial No. 230,770. Divided and thisapplication filed April 28, 1919. Serial No. 293,270.

To all whom it may concern:

Be it known that I, WALTER TI-IoMAs SMITH, a citizen of the UnitedStates, residing at Cornell, in the county of Chippewa and State ofWisconsin, have invented certain new and useful Improvements in my U. S.application Serial No. 230,770,

filed April 25, 1918, and allowed February 15, 1919. The present case isdevoted to the su ports of the scraper bar.

he principal object of the invention is to provide a simple andinexpensive form of hanger for attachment to pasting machines ofordinary construction, to hold a four sided scraper bar in position forpresenting two opposed corners thereof for simultaneous contact with twoplies of paper to separate them ahd remove surplus paste.

With the foregoing in view, the invention resides in the novelconstruction and arrangement of parts hereinafter described and claimed,reference being made to the accompanying drawing:

Figure 1 is an end elevation of a pasting I machine showing theapplication of the hangers for supporting the scraper bar.

Fig. 2 is a side elevation showing more clearly the arrangement of thehangers with respect to the old and well known parts of the pastingmachine.

Fig. 3 is a perspective view of the scraper bar and its hangers.

, In the drawings above briefly described, a pasting machine M is shownconstructed in the same manner as set forth in the parent applicationSerial No. 230,770, above referred to, and it is unnecessary to describethe several details of the machine, although it may be well to statethat it provides means for pasting two plies 1 of aper or the liketogether, utilizes a four-si ed scraper bar 2 for separating said pliesafter pasting and employs rollers or the like 3 for again forcing theplies together after surplus paste has been removed by said scraper bar2. The

present invention resides specifically in the hanger bars 4 for the bar2 and consequently the description is confined more particularly tothese parts.

The hanger bars 4 are provided with horizontal upper ends 5 adapted forattachment to well-known bearings B at the upper end of the pastingmachine M, said bars inclining downwardly and laterally from saidhorizontal ends 5 and havin their lower ends bent outwardly at 6 atright angles to the inclined parts of said bars, and then bent upwardlyat 7 in parallel relation with said inclined portions. ets are thusprovided to receive the ends of the scraper bar 2 and due to theinclination of the bars 4 and the relation of the parts 6 and 7therewith, two edges of said scraper bars will be presented to the plies4. Bolts 8 pass through the upturned bar ends 7 and through the inclinedbody portions of said bars and are positioned above the scraper bar 2,and tightening of said bolts will tightly clamp the ends of said scraperbar in place.

By constructing the hangers 4 in the novel manner shown, they may bequickly attached to pasting machines of well known construction and maybe manufactured at small cost. Furthermore, the novel formation at thelower ends of said hangers, will not only permit tight clamping of thescraper bar, but will allow this bar to be removed, turned to resent newscraping edges to the work, and t ien again secured in place.

Since probably the best results are obtainable from the exactconstruction and arrangement shown, it may well be followed but withinthe scope of the invention as claimed, numerous minor changes way wellbe made.

I claim:

1. The combination with the four-sided scraper bar of a pasting machine,of a pair of-inclined hanger bars for said scraper bar, the upper endsof said hanger bars being adapted for attachment to the pasting machine,while their lower ends are bent laterally at right angles to theinclined portions of said bars and then upwardly in parallel relationwith said inclined ortions, thus forming hook-shaped poly-si ed socketsre- Hook-shaped sockceiving the ends of said scraper bar, and boltspassing; :tln-ough saidyup' wardly ,b'ent bar end s" and through theincl inecl bticly' p0rupper ends ofsaicl hanger bars leeing benthorizontally in the 0pppsiteclirecti0n from the zlower ends "of saidbars vancl provided with openings to receive attaching bolts. 10 Intestimony whereof I have hereunto set V y n e r WALTERTHOMAS SMITH.
